虚拟示波器的设计及在实验教学中的应用

内容简介：虚拟仪器集成了计算机标准总线技术、数字信号处理技术和软件工程设计方法，是一种软件化仪器，代表着电子测量仪器未来的发展方向。文中介绍了虚拟仪器及其在实验教学中的应用，并以虚拟示波器为例，从前面板设计和程序框图设计两个方面详细地讨论了其设计与实现过程。通过教学实践表明，将虚拟仪器引入实验教学可以有效地提高学生的实际动手能力，增强学生的创造性思维能力，满足了教学要求。

Abstract：Virtual instrument integrates computer standard bus technology, digital signal processing technology and software engineering methods, is a software-based instrument, which represents the future direction of development of electronic measuring instruments. This article describes the virtual instrument and its application in the experimental teaching, and takes virtual oscilloscope as example giving a detailed discussion about its design and implementation process from the design of the front panel and block diagram. The practice shows that introduction of virtual instrument to experimental teaching can improve the hands-on practical ability of the students efficiently, enhance students＇ creative thinking ability and it meets the demand of the teaching.
